CONDITION

A key part to maintain the proper function and safe operation of the vehicle’s braking system is to perform a
visual inspection when installing brake pads, calipers and discs. The following recommendations are intended
to provide general tips for the inspection and/or installation of Toyota Complete Maintenance Care (TCMC)
front brake pads and discs. Always refer to the model specific Repair Manual and TIS publications for specific
repair instructions.

RECOMMENDATIONS

To ensure proper function and safe operation of the braking system, the following points should be followed
when inspecting and installing Genuine Toyota TCMC brake pads. Refer to PANT Bulletin 2012-049 for
specific vehicle applications for the TCMC brake pad kits.

Notes

KEY INSPECTION POINTS

Pad IIning thickness

» Wom brake pads can cause noise
and damage the rotor if not inspected

Using a nuler or @ pad thickness gauge ‘and-serviced regularly

te measure the pad lining thickness.

* Refer to the model specific Repair
Manual for standard and minimum
thickness levels

IT the pad lining thickness is less than
the minimum, the brake pads should be
replaced,

Oisc Thickness

Using a micrometer, measure the disc
thickness.

Refer to the vehicle model specific
Repair Manual for Standard and
Minimum thickness.

Ifthe disc thickness is less than the

minimum, replace the front disc.

* Many customer complaints about
disc brake operation are caused by
rotor condition issues

Variations can cause noise and
vibration when braking

Inspect rotor surface for any
abnormalities and address/repair as
necessary

| Rotor Run-out

Using a dial indicator, measure the
taleral run-out.

Refer to the vehicle model specific
Repair Manual for Maximum disc run-
‘out.

* Excessive run out can cause brake
pedal pulsation

If run-out is excessive, remove the
‘olor, tum it to the next lug, and
repeat the procedure until ihe:
minimum amount of run-out is
achieved

W the run-out still exceeds the
maximum, check the bearing play
and the axle hub run-out. If the
bearing play and hub run-out are
normal and disc thickness Is within
the specified range, use an on-
vehicle brake lathe

Disc Brake Rotor Repair

Toyota recommends using the on-car
brake lathe for repairing rotor run-out
and thickness variation,

‘This method improves rotor and hub
combined run-oul, and is the preferred
method when compared to rotor
replacement and off-the-car rotor
machining.

If the disc thickness is less than the
minimum, replace the disc

Rinse rotor with brake cleaner after
using the brake lathe to remove:
‘surface contaminants

Brake Caliper and Piston

inspect the caliper piston and boot for
rust, fluid leak or damage. If necessary,
repair or replace the disc brake caliper
assembly.

* Refer to Repair Manual for further
instructions

Lithium soap base glyco! grease

Abnormal brake pad and rotor wear
can be caused if the caliper or caliper
piston “sticks” and keeps the pad in
‘Constant contact with the rotor

Always lube piston and piston boat
before installing brake pads

Apply a light layer of lithium soap
base glycol (rubber) grease (PIN
08887-01206) to the piston and boot

‘if equipped

Make sure the pad support plates have
sufficient rebound, no deformation, no
cracks or wear and that all rust and dirt
are cleaned off,

PAD AUPPORT PLATES

Remove, inspect, and clean pad clips
to ensure @ smooth open/close
operation when the brake fs applied,
and replace if damaged

DO NOT apply any grease or
lubricants to pad clips when re-
installing

Never apply grease or ather surface
treatments to the brake pad friction
surface

Brake Pad Shims

When replacing wom pads, the supplied
TCMC anli-squeal shims must be
replaced with the TCMC pads

Apply 1-2mm thickness of the supplied
TCMC shim grease to the areas of the
pad backing plate as indicated by the
shaded areas based on plate
configuration

Do not apply shim grease to the entire
area of the backing plate

NOTE: The use of shim grease other
than the shim grease supplied with the
TCMC brake pad kits may cause
abnormal brake noise/squeal.

“For TCMC Brake Pad Kits. Use the
supplied shims and shim grease that
comes with the TCMC brake kit

Never apply grease or other surface
treatments to the brake pad friction
surface,

Never use old or worn shims. They
may have cracks or damage that is
not clearly visible to the eye

Never apply anii-seize or other types
of non-approved grease to the shims.
